PXI/MOST interface ensures end-of-line test quality

Many different suppliers are developing electronic control units (ECUs) providing an interface to the MOST bus. Detailed compliance testing is required in order to eliminate faults and to ensure the correct behavior of different MOST interfaces in the same network. By focusing on the challenge of testing, the PXI standard and simultaneous test philosophies have led to the development of the first PXI/MOST150 interface.

The ECUs of a modern car are all linked together via various networking technologies like CAN, LIN, or FlexRay for safety critical applications. In the case of infotainment and multimedia systems, MOST has established itself as the de-facto standard, distinguished by high bandwidth and electrical robustness. MOST150, its third generation, makes high demands on automotive development and testing environments. This article puts the focus on manufacturing, burn-in/run-in test, and reliability testing of ECUs implemented with a MOST interface. The upcoming problems for hardware, industrial standards, and test strategies, and the methods for dealing with them, are also discussed.
